Re: weight-set defined for some OSDs and not defined for the new installed ones

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a cluster where for some OSD the weight-set is defined, while for
other OSDs it is not [*].

The OSDs with weight-set defined are Filestore OSDs created years ago using
"ceph-disk prepare"

The OSDs where the weight set is not defined are Bluestore OSDs installed
recently using
ceph-volume


I think this problem explains while I am not able to use anymore the
balancer (after having added these new OSDs).

Any "clean" procedure to fix this mess is appreciated !

Thanks, Massimo

Please, show your `ceph osd df tree`.
